GTX 660 vs Radeon HD 2600 XT: a cross-generation spec comparison. These GPUs come from different eras (2012 vs 2007), so direct benchmark comparisons are not meaningful. The table shows their specifications side by side for historical and architectural context.
Different eras, different missions
These two parts do not compete head-to-head: GTX 660 (2012, Desktop) and Radeon HD 2600 XT (2007, Desktop) come from different generations or market segments, so modern game benchmarks do not apply to both. The specification table above is best read as architectural context — process node, memory technology and power budgets show how far GPU design has moved.
Specifications at a glance
GTX 660 carries 2 GB of GDDR5 against 262 MB of GDDR3 on Radeon HD 2600 XT, with board powers of 140 W and 35 W respectively.
The verdict
Both are credible choices in the graphics card comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Graphics cards are compared on 3DMark Time Spy scores, average gaming frame rates at 1080p/1440p/4K, FP32 compute throughput, VRAM capacity and type, memory bandwidth, board power (TDP) and launch MSRP — plus AI workload throughput (Stable Diffusion iterations/s and local LLM tokens/s) where measured. Vintage and server GPUs without modern benchmark results are compared on specifications only, clearly labelled. Frame rates are averages across a game suite at high settings; specific titles vary.
